The project known as OpenOffice today is actually Apache OpenOffice and is being developed under Apache’s umbrella under the Apache license. In 2011, Oracle gave the trademarks and code to the Apache Software Foundation. Most Linux distributions, including Ubuntu, switched their bundled office suite from to LibreOffice.

LibreOffice was a fork of and is built on the original code base. Most outside volunteers - including the contributors to Go-oo, who contributed a set of enhancements used by many Linux distributions - left the project and formed LibreOffice.

They renamed the proprietary StarOffice office suite to “Oracle Open Office,” as if they wanted to cause confusion, and then discontinued it.

In 2011, Sun Microsystems was acquired by Oracle. The project continued with help from Sun employees and volunteers, offering the free office suite to everyone - including Linux users. In 2000, Sun open-sourced the StarOffice software - this free, open-source office suite was known as. Sun Microsystems acquired the StarOffice office suite in 1999.
